VILILIAM H.

(These springs aresimply straps of steel fastened at one end to the cross pieces of theframe of the carriage and supported about midway of their length, by across strap of iron or steel). F, F, is the curved lever or eccentricsemicircle, which revolving with the shaft and playing against thefriction rollers E, E, moves the carriage backward and forwardhorizontally beneath and parallel with the bottom or floor of thecistern. G is the shaft which should be in size about 39j inches square.Fig. 3 also shows with sufcient accuracy the relative positions of thefiller and curved lever upon the shaft. As the shaft revolves, thecurved lever playing against one of the friction rollers moves one endof the carriage out to deliver the mold, and places the valve under theopening at that end in its stead, and as the curved lever leaves thisroller, the filler commences passing over the mold under the oppositeopening to fill it, and by the time the filler has accomplished this,the curved lever has reached the other friction roller to move that endout for the delivery of its mold and vice Versa. The filler isrepresented in Fig. 3 by A the handle and B, the blade or inclinedplane; (to give an idea of its dimensions we will state the size of theone from which this is drawn), length of shank or handle 2 feet fromcenter of shaft extending across the back near the middle, to the outeredge of the blade; blade ll in. by 17 in., rounding on the outer edgereducing the ends to l0 in. in width; it may however be ymade of otherdimensions suited to the size of the cistern and of the openings in thebottom. v

lraised edges of the floor on which the plank of the cistern rest. Thedotted lines represent the additional openings and the partitions (iffixed partitions be used) when two mold cars are used. D the shaft or`hole where the shaft passes through.

The foregoing isa full description of the machine as used with one moldcar or carriage; it may also be worked with two carriages or mold carsin the manner described as follows:

Fig. 5 represents in perspective the second carriage (drawn also on ascale of an inch to the foot, with suflicient accuracy to give an ideaof its proportions,) with the first carriage as it runs across it,showing the relative positions of the two carriages at the moment when,as the shaft revolves, the curved lever (which moves both carriages F,F, Fig. 3) has passed by the roller under the upper valve of the upperor i'irst carriage and thrown or moved that end out far enough todeliver its mold, and is just commencing on the next, being the righthand end of the second or lower carriage to move it-s mold out and so onof the rest, one after the other; A A A A the rst carriage with itsvalves and friction rollers (as represented in Fig. 3) B, B, B, B, theframe of the second carriage running under that of the first; C, Csupports or elevation of valves; D, D, surfaces or valves extending overtheir supports and elevated higher than the valves of the firstcarriage; under the valves are friction rollers (represented by` dottedcircles) as in the other; the space between the supports of the valves(at the sides) of the second carriage; is greater than that of the first(see Fig. 5). This second carriage is supported and moves like the firston 2 rollers placed on the other two opposite sides of the cistern orframe, and runs across beneath the first carriage except its valveswhich rise above the valves of the iirst carriage and close up to theunder surface of the floor of the cistern. Bot-h carriages are alike inprinciple and nearly alike in construction except the differences abovepointed out. The second carriage has the same alternate horizontalmotion as the first and is moved by the same curved lever playingagainst its friction rollers (so placed as to be even or level with thefriction rollers on the other carriage). When two carriages are used,the floor of the cistern must, of course, have four orifices orapertures for the mortar to pass through, one at each of its four sides;two of these openings, those under which the first carriage runs, musthave necks or raised edges on the under surface, so as to meet thevalves on the first carriage, which first carriage, when two are used,runs lower (under the floor) than when used alone, (say to an in.) toallow the corners of the valves on the under or second carriage to passover the corners of those of the first and to prevent the valves on thetwo carriages from hitching or coming in contact with each other; (thesenecks may also be used with advantage when there is but one carriage).rlhe sides of the frame of the second carriage are deeper from thevalves outward than the rst, (as the drawing will show) so as to .u so

raise the molds even With its valves. The 2. And `We also claim themanner in which molds on both carriages are illed by the We havecombined With the cistern and its same filler (described in Fig. 3).revolving shaft for tempering the mortar,
